Melinda Lopez is rescued after falling from of her boyfriend's shrimp boat.

After falling overboard Tuesday from the shrimp boat where she worked, Lopez swam and floated until she reached safety at an oil platform, spray-painted a distress signal and managed to activate an alarm system to summon help.

"I just had to stay strong. I didn't want to go like that," the 32-year-old Lopez said in a story in Friday editions of The Victoria Advocate. "I didn't want to be eaten by fishes. I was really scared."

Lopez's ordeal began 70 miles off Galveston in the Gulf of Mexico, where Lopez was climbing around the 76-foot shrimper Ike and Zack to find a spot to read. She slipped and fell in the water without a life jacket.

Neither the boat's three-man crew nor those of other boats that floated past heard her cries.

"The water was rough," she said in the online edition of the Houston Chronicle, adding that she was bumped by large fish. "The waves were coming over my head."

Lopez said she swam all night, following a distant sound and finally reaching a foghorn on the offshore rig about daybreak Wednesday. There, she found a moldy loaf of bread, other food and water - and some black and white paint.

She painted an SOS on the platform, made a balloon out of a black trash bag and spray painted it with another plea for help. She was also able to trigger an alarm system on the platform, which activated sirens and lights.
